Free Dynamic DNS, DDNS, on your Domain Name

As many of the Internet Service Providers give Dynamic IP with their Internet Connections, Dynamic DNS has became an essential problem for the system administrators at Small Medium Enterprises. A Dynamic DNS Service will allow you to always direct a domain name to a computer even if your IP address changes regularly.

Dynamic DNS is used when you want to host a small website on your personal computer, when you want to access office DVR online, host your erp systems on your office server…. etc and you have got a changing IP for your office internet connection.

There were many free players in the Dyanamic DNS market till last year who provide second level dns names with their domain . Now Dyn.com,TZODns and many others has stopped their free services. changeIP.com,no-ip.com, afraid.org etc still provide secondary level DDNS services.

DNSExit.com is one of very good services so far, if you need to point your Primary Domain / Top Level domain to DDNS, or if you need to point any subdomain to DDNS. “DNS Exit provides 100% free static or dynamic DNS Services to your top level domains. Our DNS still keeps 100% uptime history since we started in 1998.” is their advertisement on the website.

Tutorial Case

For our case, we had to host Zsenda.com on a webserver with static IP, and we needed to host ‘errata.zsenda.com’ on DDNS which points to our bug tracking system hosted in our office system with a Dynamic IP.

Opened Zsenda.com’s DNS Editor and create four ‘NS’ entries [Name Server Entries] for ‘errata.zsenda.com‘ and pointed them to ns1.dnsexit.com,ns2.dnsexit.com,ns3.dnsexit.com,ns4.dnsexit.com respectively.

use “DNS Express Setup” and entered the domain name ‘errata.zsenda.com’ and checked the value ‘ IP Address is Dynamic’. They had already filled “Your IP Address” field with my current Public IP and created DNS.

Next it was verification by DNSExit, that domain is already pointed to Name Servers of DNSExit.com
